We would suggest one of our 16 gauge - commercial quality stainless steel sinks. We have three main collections which differ with their radius corners: UrbanEdge with 0mm square corners, J7 with 7mm corners and Classic with 29mm corners. Each one of them brings a different style to the kitchen. Standard models are intended to be installed undermount but can be easily modified with a simple option to turn them into topmount sinks. And to answer your space concerns, our products offer is working by increments of 3''. That means you can find a sink every 3'' from 9'' to 36''. If no dimension fits your kitchen cabinet, we still offer a Signature program to manufacture any custom stainless steel sink, according to your drawing.

Good luck with your project!
